A hilarious--and slimy--alien adventure (set on Earth) that the bestselling author of Zombie Chasers, John Kloepfer, calls fast paced, out-of-this-world fun Selected by the Wisconsin Library Association for Outstanding Achievement in children's literature.

When Margot Blumenthal removes a bright blue slug alien attached to Mateo Flores's back, the school play co-stars know it's definitely not going to be a regular day at West Cove Middle School.

They reluctantly team up and soon discover that the mayor and countless other adults, including Mateo's dad, are infected--which means that West Cove, and possibly all of Earth, is in danger.

What will they (and their new scientist friend) do? Ditch class and protect humankind, of course--because one unexcused absence doesn't matter when the world is at stake

This stand-alone middle grade novel is fun, silly, and full of adventure. Young readers will speed through it...if they can stop laughing long enough to turn the page.
